Chiral symmetry breaking on the lattice [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2017
We review important aspects of QCD in the continuum and on the lattice and take a look at the fate of its symmetries with an emphasis on chiral symmetry breaking on the lattice.

Crystallization-driven template autocatalysis induces mirror symmetry breaking and amplification [PDF]

open access: yesNature Communications
A plausible hypothesis for the origin of biological homochirality invokes chiral symmetry breaking, transfer, and amplification driven by autocatalysis. Here we experimentally demonstrate that crystallization-driven template autocatalysis (CDTA) induces ...

Chiral Symmetry Breaking and the Masses of Hadrons: A Review

open access: yesSymmetry, 2023
The masses of hadrons in the vacuum, where the chiral symmetry is restored, and in the medium are generally different even when the changes in the order parameters of chiral symmetry are the same. Here, we first discuss the relation between the hadron masses and the chiral symmetry breaking in approaches based on operator product expansion (OPE).

STRANGENESS AND CHIRAL SYMMETRY BREAKING [PDF]

open access: yesModern Physics Letters A, 2011
The implications of chiral symmetry breaking and SU(3) symmetry breaking have been studied in the chiral constituent quark model (χCQM). The role of hidden strangeness component has been investigated for the scalar matrix elements of the nucleon with an emphasis on the meson–nucleon sigma terms.

Symmetry-breaking in Chiral Polymerisation [PDF]

open access: yesOrigins of Life and Evolution of Biospheres, 2005
We propose a model for chiral polymerisation and investigate its symmetric and asymmetric solutions. The model has a source species which decays into left- and right-handed types of monomer, each of which can polymerise to form homochiral chains; these chains are susceptible to `poisoning' by the opposite handed monomer. Homochiral polymers are assumed

Chirality transfer from a 3D macro shape to the molecular level by controlling asymmetric secondary flows

open access: yesNature Communications, 2022
External physical forces can bias a spontaneous symmetry breaking process but whether the shape of a reactor plays a role in chiral symmetry breaking processes is an open question. Here, the authors demonstrate chirality transfer from the chiral shape of

Interplay between nuclear chiral and reflection symmetry breakings revealed by the lifetime measurements in 76Br

open access: yesPhysics Letters B, 2022
Nearly degenerate positive-parity doublet bands and several E1 transitions between positive- and negative-parity bands have been identified in 76Br. These experimental observations are interpreted as the coexistence of chirality and octupole correlations,

Chiral symmetry breaking in QCD [PDF]

open access: yesZeitschrift für Physik C Particles and Fields, 1987
By applying bifurcation theory to a truncated Dyson-Schwinger equation for the quark propagator in massless QCD, we show that dynamical symmetry breaking occurs at a certain critical value of the coupling constant. Essential ingredients are (a) an effective dynamical mass for the gluon, and (b) a running coupling constant.

Gapped Chiral Fermions

open access: yesPhysical Review X, 2021
In principle, there is no obstacle to gapping fermions preserving any global symmetry that does not suffer a ’t Hooft anomaly. In practice, preserving a symmetry that is realized on fermions in a chiral manner necessitates some dynamics beyond simple ...

Non-Abelian anomalous constitutive relations of a chiral hadronic fluid [PDF]

open access: yesEPJ Web of Conferences, 2022
We study the constitutive relations of a chiral hadronic fluid in presence of non-Abelian’t Hooft anomalies. Analytical expressions for the covariant currents are obtained at first order in derivatives in the chiral symmetric phase, for both two and ...
